ADJUSTABLE STAND FOB. DEFLEGTING-BARS.

Application filed January 20, 1910.

To all whom it may concern:

Be it known that I, EDWIN C. LARRY, a citizen of the United States, andresident of Harvey, county of Cook, and State of Illinois, have inventedcertain new and useful Improvements in Adjustable Stands forDeflecting-Bars, of which the following is a specification, and whichare illustrated in the accompanying drawings, forming a part thereof.

The invention relates to railway switch and signal appliances, and morespecifically to means for supporting and guiding curved bars, termeddeflecting bars, such as are employed for changing the direction of therods and pipes used for operating switches and signals by mechanicalmovement.

The object of the invention is to provide a supporting stand of the kinddescribed which may be adjusted to receive deflecting bars of differentcurvature.

The invention is exemplified in the structure to be hereinafterdescribed and illustrated in the accompanying drawings, in which Figure1 is a plan view of railway track equipment showing a plurality ofstands embodying the features of improvement provided by the invention;Fig. 2 is a side elevation of the apparatus illustrated in Fig. 1; andFig. 3 is similar to Fig. l, but shows the parts diiferently adjusted.

A series of rods such as are employed in railway track equipment foroperating switches and signals by mechanical movement, is illustrated inFig. 1 of the drawings, at 10, 11, 12, and in Fig. 3 at 37, 38. As shownin Fig. 1, these rods are formed in sections 13, 14, and are deflectedthrough a considerable angle by interposing between the sections 13, 14of each rod, a curved bar 15 having its ends connected to the sections13, 14, by pivots 39, 40. In Fig. 3 of the drawings, the rods 37, 38 areshown as being formed in sections 16, 17 and as being deflected througha less angle than are the rods 10, 11, 12, illustrated in Fig. 1, byinter-posing between the sections 16, 17, a deflecting bar 18 of lesscurvature than the deflecting bar 15.

In carrying out the invention, a jointed stand adapted to serve as asupport and guide for deflecting bars, and which may be adjusted toreceive bars of diflerent Specification of Letters Patent.

curvature, as the bars 15, 18, is provided. As shown in Fig. 1 of thedrawings these stands are generally designated by the numerals 34, 35,36. Similar stands, differently adjusted, are shown in Fig. 3 at 41, 42.Each of the stands 34, 35, 36, and 41, 42, comprises a pair of basemembers 19, 20 connected by a bolt 21. For guidingly supporting thedeflecting bars, as 15, 18, each of the base members 19, 20 carries apair of studs, 22, 23, upon which are mounted roller bearings as 24,adapted to engage the defleeting bars upon opposite sides. The studs 22,23 are most conveniently mounted in the base members, as 19, 20, as bybeing pro vided with a reduced end 25 (Fig. 2) adapted to enter anaperture in the corresponding base member and to be headed over belowthe base, as at 26, whereby the base member is gripped between the head26 and a shoulder 2'? formed on the stud. Preferably, caps, as 28, areapplied to the studs 22, 23, above the roller bearings 24, and aresecured in place thereon by cotter pins 29. As shown, the caps 28 forthe studs 22, 23 mounted on each of the base members 19, 20, are formedintegral, and this integral cap structure is provided with dependingflanges 30, which substantially cover the roller bearings 24, and arenotched between the said bearings, as shown at 31 (Fig. 2) to receivethe deflecting bar, as 15.

In erecting the stands for use upon a railway track, the base members19, 20 are turned upon the pivot 21 to the required relative position toreceive a deflecting bar 15, 18 of the desired curvature and are thenpermanently secured to the track, as by being fastened to a bed plate 32by bolts 33. Most desirably each of the base members 19, 20 is ofangular shape and has parallel bearing surfaces 43, 44 upon oppositesides. When so formed a plurality of stands may be mounted upon aeonnnon bed plate 32, additional stands, 34, being properly positioned,when one stand, as 36, has been secured to the bed plate, by simplylaying them upon the bed plate with their bearing surfaces, as 43, incontact with the bearing surfaces 44 of the base members 19, 20 of thestand already secured in place. By reason of the fact that the bearingsurfaces 43, 44 of each of the base members 19, 20 are parallel, eachstand, when fitted to an adjacent one in the manner just described. willbe thereby properly adjusted to receive a deflecting bar of the samecurvature.

I claim as my invention 1. A deflecting bar stand comprising incombination a pair of pivotally united base members, and a pair ofcooperating guide bearings for a curved deflecting bar mounted on eachof the base members.

2. A stand for deflecting bars comprising in combination a plurality oflike pairs of relatively adjustable base members, each of such membersbeing of angular shape and having parallel bearing surfaces uponopposite sides for contacting with corresponding members of adjacentpairs, and a pair of cooperating guide bearings for a curved deflectingbar mounted. on each of such members.

3. A stand for deflecting bars comprising in combination a plurality oflike pairs of pivotally united base members, each of such members beingof angular shape and having parallel bearing surfaces upon oppositesides for contacting with corresponding members of adjacent pairs, and apair of cooperating guide bearings for a curved deflecting bar mountedon each of such members.
